Microsoft applications use both of these to try to determine if a font
is likely to support a certain range. Some fonts do not properly set
those values but most do, especially common ones.

Subject: the Unicode range and code page range bits in the TrueType OS/2
table

Dear i18n folks in Unicode.org

Do we know ANY application on ANY platform use the Unicode range or code

rage field in the TrueType OS/2 table to support different langeuags ?

Does Microsoft applications depend on that ?

Deborah:
How about MacOS and Mac OS Apps

Any Linux application use that ?

Ken:
Do you know any Adobe software depend on that?

I heard a rumer said that those bits are usually unset and keep as 0.
But I found that some of the font are set if I use ttfdump to look at
them.

Thanks
